DETACHABLE PIPE OR HOSE COUPLING.

To all whom it may concern:

Be it known that we, GEORGE JAMES, SAMUEL BENSON, and WILLIAM\V1LsoN,citizens of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new and use;

ful Improvements in Detachable Pipe and Hose Couplings, of which thefollowing is a specification.

Our invention relates to, a detachable ipe or hose coupling and theobjects thereof are to provide a coupling which will be light, compactand inexpensive, which may be instantly coupled or uncoupled without theuse of wrenches or special tools, and in which the coupling members areidentical in construction and operation.

Our advantages in the construction and operation will appear in thecourse of the following description, reference being had to theaccompanying drawings, forming a part of this specification, in whichlike nate like parts throughout the several gures, and in which Figure 1is a side elevation of two coupling members constructed in accordancewith my invention, in the coupling position, and illustrating one formof fastening means, Fig. 2 is an end elevation thereof, Fig. 3 is acentral longitudinal sectional view taken through a pair of couplingmembers in a coupling position and illustrating another form offastening means, and Fig. 4 is an end elevation thereof.

In the practical embodiment of our invention we provide a pair ofcoupling members 1 and 2 each comprising a tubular portion 3 having acircular flange 4 extending there from. The flanges 4 are each providedwith dovetail slots 5 and dovetail projections 6 opposite said slots.The tubular portions 3 of the members 1 and 2 are provided each with acentral bore 7 set for a distance from the outer end thereof, for thereception of a pipeorhose secured therein, and provided adjacent theirinner ends in said bore with circular cut-out portions in which elasticgaskets 8 are adapted to fit and to abut one another when the members 1and 2 are coupled as shown in Fig. 3. Seated in circular recesses 9extending around the cutout portions in which the gaskets 8 are placed,are splitspring rings 10, adapted to tightly clasp the exterior surfaceof the gaskets 8 to hold the same within their respec- Specification ofLetters Patent.

tive members when the same are uncoupled. Each of the dovetailprojections (3 are provided with forwardly extending noses 11 havingcurved recesses in the upper faces thereof for the reception of suitablefasten ing means after engagement through the dovetail slots 5. In theform of fastening means shown in Figs. 1 and 2, a curved springretaining bar 12 is provided upon eye-loop at one end thereof, and saidop being secured through and swinging upon an eye-bolt l3 threaded orotherwise secured within the flange 4 of its respective coupling member.The retaining bars 12 are each secured as described on one side of theslots 5, the flan e 4 being provided on the opposite side of said slotswith a retaining block 14 provided with a recessed inner face andadapted to receive the free end of the retaining bar '12 from underafter the same has been associated over the nose 11 when the couplingmembers 1 and 2 are assembled. Thus the same may be firmly locked.

The fastening means illustrated in Figs. 3 and 4 comprises a retainingplate 15 carried by each of the members .1 and 2. arranged oppositetheir slots 5 and having spring arms 16 curved about the tubularportions 3 of said members and having theirends pro ecting withinopenings in an enlarged bracket portion 17 opposite the dove tailprojection 6.

Having thus fully described our invention,

we claim:

1. The combination in a coupling of the character described, of couplingmembers of identical construction, each comprising a tubular portionhaving a central bore and an outstanding circular flange at one endthereof, adapted to abut the flange of the oppos ing member, saidflanges being provided with oppositely disposed. wedge-shaped slots andwedgeshaped projections adapted to be engaged by relatively oppositesidewise movements of said members, said slots being formed through theentire width of said flanges, said projections being of substantiallythe same width as said flanges and being provided with forwardlyextending portions beyond said slots, and locking members pivotallymounted upon said flanges and spanning said slots to engage'over saidprojecting portions, substantially as described.

2. The combination in a coupling of the character described, of couplingmembers of identical construction, each comprising a tubular portionhaving a central bore and an outstanding circular flange'at one endthereof adapted to abut the flange of the opposing member, said flangesbeing provided with oppositely disposed wedge-shaped slots andwedge-shaped projections adapted to be engaged by relatively oppositesidewise movements of said members, said slots being formed through theentire width of said flanges, said projections being of substantiallythe same width as said flanges, and being provided with forwardlyextending ggl'tlOl'lS beyond said slots, said flanges being urtherprovided with projections extending therefrom at one side of their saidslots, and

locking members pivotally' mounted upon said flanges at the oppositesides of their said slots to their said projections and adapted forengagement over the said forwardly projecting portions of saidWedgeshaped projections and beneath the said flanged projections, tolock said members together, substantially as described.

In testimony whereof we affix our signav tures in presence of twoWitnesses.
